Filter systems for an optimal energy balance
A wind turbine is only profitable if the rotors rotate and the turbine starts to generate electricity. Various filtration systems from Filtration Group clean the air, the lubricating oil and the water in the Nacelle to which the turbine is attached, in the tower and in the transformer platform in order to meet the requirements of weather conditions, technology and environmental protection.
Medium and high pressure filters in the brake system, in the azimuth drive and in the pitch system clean the lubricating oils, ventilation filters and the ambient air sucked in from dirt particles and dust. In the Nacelle and in the tower, air conditioning systems, so-called conditioning units, ensure that sensitive control units do not overheat during operation. For fuel processing and to prevent contaminated water from getting into the environment, oil separators, fuel processing systems and sea water filters are used in the transformer platform, the functioning of which is based on the principle of separation.
Together we are making wind power…
…safer, because we help you to avoid malfunctions and prevent failures of control elements
…healthier, because our products meet the preconditions for acquiring energy from a regenerative source both on land and on the open sea and under hostile weather conditions
…more productive, because we ensure smooth operation of the wind power system.
Filtration Group makes the core of wind energy clean
On the high seas or in the middle of the pampas, wind turbines are constantly exposed to the weather. Their smooth functionality even under adverse circumstances is the basic requirement that enable electricity to be generated from wind. Filtration Group’s filter systems remove dirt particles from the air, operating fluids or surface water that can impair the efficient functioning of the system.
The delicate alignment of the rotor blades to wind direction and speed has a critical influence on the efficiency and service life of a wind turbine. To consistently ensure the functionality of the pitch system in the rotor hub, the hydraulic fluid in the motors must be clean. The filter solutions from Filtration Group create an effective dirt barrier, thus ensuring the smooth operation of the pitch system.
The gearbox in a wind power system transforms the low rotational speed of the rotor hub into a higher speed for the generator. Only when this vital part of the system is working optimally, the wind is turned into electricity. Filter elements with the advanced PulseShieldTM technology filter the oil with a fineness of up to 3m, thus reliably separating the finest particles and oil aging products. This ensures a low wear and tear and thus also low-maintenance operation of the wind power system
The performance capacity of a wind power system also depends on the precision with which the rotors are aligned in facing the wind. To ensure that the nacelle moves together with the changing direction of the wind, the servomotor of the azimuth drive must run reliably. Filtration Group connects a service indicator to various customized solutions for the purification of the intake air and the hydraulic fluids, thereby facilitating efficient remote control of the system.
Before excessive centrifugal forces act on the rotor blades, it is sometimes necessary to slow down or switch off the wind turbine in extreme wind conditions. A precise braking system slows the wind turbine down or stops it safely and quickly, thus preventing possible damage. So that the brakes are ready for use in an emergency, no foreign particles may accumulate in brake and hydraulic fluids. Filtration Group supplies suitable filter solutions that keep the brake system permanently intact.
In the nacelle of each wind turbine, drive and brake systems are used for the rotors and the nacelle itself. A climate control system keeps the equipment from overheating during continuous operation and harming the viscosity of the hydraulic fluids. But the ambient air that is drawn in must be filtered in advance. The nacelle conditioning unit from Filtration Group makes sure that dust, pollen and insects do not enter the nacelle, thereby facilitating the reliable continuous operation of the system.
For conditioning in critical control units and electronic systems in the towers of onshore and offshore systems, Filtration Group has developed a special Tower Conditioning Unit. It is used to filter out dirt, salt particles and moisture from the ambient air that is taken in. These particles collect on the patented DropSafeTM pocket filter, while the water is separated on the hydrophobic filter material using the proven coalescer process and accumulates in reservoirs upstream of the filter. The effective filter thus prevents corrosion on the turbine and ensures the efficient operation of the system.
Rain and spray, which accumulates in leak basins under the transformers, are often mixes with process oils. Before the water is drained into the ocean, components from Filtration Group filter the harmful substances out in accordance with the most stringent environmental standards. Filtration Group also offers efficient systems and seawater filters to separate salt water from oil and fuels. That in turn ensures the smooth operation of the system.
